Frequently asked questions
What driver do I need for this motor?
It is a two-phase stepper, so it needs a bipolar stepper driver that can supply 6.0 A per phase. Set the driver's current limit according to its datasheet and the motor rating.
Which shaft option should I check before mounting a pulley or coupling?
The shaft is 12.7 mm or 14 mm in diameter, with a flat or keyway option and a length of 32 mm or 37 mm. Confirm the bore of your coupling or pulley matches before mounting.
